rIhis invention relates to glare shields, particularly those used inside amotor-vehicle j and adapted to be adjustably positioned by the driver to cut off the glare of approaching Vlights, and, when not in use, to be moved upwardly out of the normal line of vision. An.

important object of the present invention is to make a shield whereinthe principal operating part-s are concealed from view and are also protected from exposure to the elements.

In this connection my invention contemplates the provision of a shield which is compact in shape and can be readily attached to any motor vehicle in an expeditious manner. In the drawings, Fig. 1 isa front elevation and Fig. 2 is a side elevation of a shield embodying my invention; Fig. 3 is an enlarged sectional view taken through the shield on a plane indicated by the yline 33 in Fig. 2; Fig. 4 is a sectionV taken through that portion of the shield indicated in Fig. 3, and more particularly, on a plane indicated by the line 4-4 in Fig. 3; Fig. 5 is an end view of part of the Vindexing mechanism shown in Fig. 4; Fig. 6 is a sectional view similar to Fig. 3 and showing a modified form of 'indexing mechanism; Fig. 7 is a section taken through the apparatus shown in Fig. 6, and more particularly, on a plane indicated by the line 7-.7 in Fig. 6.

My glare shield is shown as having a visor f 10 which may be made of any transparentmaterial and which may be mounted within the boundary frame 11 (mostly U-shaped in cross-section) which in turn is arranged to be pivotally mounted uponsupporting arms 12. These arms are adapted to be attached to the interior of a motor vehicle in any convenient manner. Y

A shaft 13 extends between the arms and functions to cooperate with the visor frame to provide a pivotal connection with the arms. An indexing mechanism is associated with the shaft and is arranged to hold the visor in any adjusted position. One form of 'indexing mechanism, as indicated inFig.' 3, embodies a pair of cooperating members 15 and 16, one of which is preferably an integral part of the arm while the other is splined to the shaft 13. A spring 17 also mounted 0f the shaft.

*Within the arm functionsto urge the members i into operative engagement and permits the turning of onewith relation to the other for indexing purposes. The member 16, as shown in Fig's. 4 and 5, is a yradially corrugated cir- 55 4cular member having a fiat portion 18 which permits sliding of the member along the shaft while itis being rotated therewith. Y

' rIo make a'complete closure forthe indexing mechanism, I have shown each arm as having an enlarged bearing 20, adjacent the end thereof.y This bearing is in the nature of `a cylindrical `housing having sufficient length to enclose'the vindexing members and associated spring. .'One end of the bearing 65 isshown as being closed by a cap 21, while the other y'end is shownas being closed by anotherpcap inthenature of a nut 22, which Y is arranged to bethreaded onto the end 23 he end portions`2'4 of the visorjframe 11 are iattened andare arranged to t over the shaft and to be rigidly yconnected therewith, as by a splined connection similar to that indicated at 18 on the member 16, and 75 Y adapted to be locked in place by the cap 22.

A washer 25 completes the assembly and provides an abutment'for the spring 17. Y

If desired, the indexing mechanism could be mounted only on one arm, but to insure a rigid construction I prefer to mount the mechanism ineach arm in substantially the same way. l

In Figs. 6 and 7 ,I have shown a modified form of indexing mechanism which com-'185 kprises a pair of plungers 26 which are slidably mounted within the passageway 27 withinthe housing 20. In. this case, the housing is only bored sufficiently to permit turning of the shaft 13A, so that ample metal will be provided topermit theuse of spring-actuated plungers l therein. These plungers form one member of the indexing mechanism. The other member is in the nature of a washer 28, having lrecesses 29 disposed therein at spaced intervals. The centersof these recessesare on a circuit which` is concentric with the washer, wherefore the plungers will successively engage the recesses as the member 28 is rotated. The springs 30 which are 100 disposed behind the plungers have suieient force to hold the visor in any adjusted position. The member 28 may also be splined ontorthe shaft as by a straight portion 31, similar to that illustrated in F ig. 4. The remaining construction of the shield is substantially the same.

A shield embodying my invention is'fad- Vantageous in that all indexing mechanism, including the springs, can-be enclosed'within the supporting arms. This makes ra neat and compact construction and at the same time provides a shield wherein the operating v parts are completely enclosed. Thus I can pack the interior of each arm with lubricant and adequately protect them from exposure to the elements. y

`I claim: y i

A glare shield having in combination,u a pair of independent supporting arms, each arm having a `passageway :extending therethrough, a shaft extending. between and throughV each'of said arms and projecting beyondthe end of each arm, an indexing couple between the shaft and each arm, said couple having one member rigidwith the` associated armand having the other member rigid With the shaft, a spring mounted in each passage- Way and operating upon the members of the couplerto hold them in engagement VWith each other, a visor, ay frame therefor,` a frame eX- tension rigidlymountedupon the shaft and means outside the frameand 4engaging the shaft for` holding all of said members in assembled relationship.

l In testimony whereof, I hereunto aixmy signature. Y
